1. shine, brighten, burnish, buff, smooth. 8. shine, gleam. Polish, gloss, luster, sheen refer to a smooth, shining, or bright surface from which light is reflected. Polish suggests the smooth, bright reflection often produced by friction: rubbed to a high polish. Gloss suggests a superficial, hard smoothness characteristic of lacquered, varnished, or enameled surfaces: a gloss on oilcloth, on paper. Luster denotes the characteristic quality of the light reflected from the surfaces of certain materials (pearls, silk, wax, freshly cut metals, etc.): a pearly luster. Sheen, sometimes poetical, suggests a glistening brightness such as that reflected from the surface of silk or velvet, or from furniture oiled and hand-polished: a rich velvety sheen.
